POCKET-STAM P.

SPECIFICATION forming part of Letters Patent No. 357,473, dated February 8, 1887.

Application filed January 27, 1886. Serial No.189,978. (No model.)

To all whom it may concern.-

Be it known that I, LE EIIRLTCH, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement inPocketStamps, of which the follow-' ing is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which-- Figure 1 is a perspective view of the stamp in its normal position, or open. Fig. 2 is a side View of the same when closed.' Fig. 3 is a longitudinal section showing the stamp open.

The stamp has a U-formed bar, A, of sufficient strength to withstand the pressure brought upon the dies in making the impres- B isthe engraved die, which is supported by spring screws C O, which pass easily through the upper portion, a, of the bar A, so that theyhave free vertical movement therein; but

the fit is so close that the screws act as accurate guides to the die in its vertical movements.

D are spiral springs which surround the stems of the screws, and whose ends bearrespectively on the portion a of bar A and beneath the heads ofthe screws 0. The springs act to sustain the die B in contact with the 3o arm or portion a when the parts are in the normal position, and to restore the die to this place when the cam s are raised. The arm or portion a of the bar A serves for the attachment of the lower or soft die, E, which may be dropped into a cup, F, secured by screws G, or by other means, to the arm or portion a, or may be made in one piece with the arm a.

H is a lever, which is forked so as to extend down each side of the arm a, and is hinged to the arm by a pintlc, I, passing through the 40 cams h h at the ends of the lever. These cams are so shaped that when the lever is in the position shown in Fig. 3 the cams do not bear upon the die B, but when the lever is in the position shown in Fig. 2 the dies are pressed 5 hard together. The salient part h of each cam comes in contact with the die B when the stamp is closed, as shown in Fig; 2, and thus the further movement of the cam-lever is prevented.

In place of the screws 0, pins may be used, secured to the die by solder or in any other manner, and in place of the spiral springs D a spring or springs of any well-known form may be used.

1 claim as my invention-- 1. The combination, with the bent bar A, having the arms a and a, the fixed die secured to the arm a, and the movable die secured to the arm a, of the operating-lever H, bifur- 6c cated for embracing the arm a, and a cam at the extremity of each prong of the said bifurcated lever, as and for the purposes set forth.

2. The combination, with the bent bar A, 65 having the arms a and a, the fixed die secured to the arm a, and the movable die, of the operating-lever H, bifurcated for embracing the arm a, to which it is hinged, and having a cam at the extremity of each of its prongs 7o 1 and pins for guiding the movable die located upon opposite sides of the hinge of the operating-lever, substantially as set forth.

LEO EHRLICH.
